Sounds like you did good by going through all the other potential issues, but I would ask if you greased the saddle rails and seatclamp parts where they contact each other. Although it squeaks when just flexing the frame off the bike it still could be an issue especially if you're using the saddle to hold on to while flexing the frame. I would double check the torque on your BB as it sounds like you may using too much torque as max should be about 7kgf but I may be getting My kgf/N-m/Ft-lbs numbers off.
